I need to learn more about broadcasting on a socket.

I have installed an additional network adapter on my computer and assigned it IP address 192.168.50.10. I have connected one device to that networkadapter, the device's IP address is 192.168.50.50.

Now if I run the following code:

IPEndPoint ipEP = new IPEndPoint(IPAddress.Parse("192.168.50.255"),0x77FE);				
Socket s = new Socket(ipEP.Address.AddressFamily, SocketType.Dgram, ProtocolType.Udp);

s.SendTo(msg, 0, msg.Length, SocketFlags.None, ipEP);
				
IPEndPoint senderEP = new IPEndPoint(IPAddress.Any, 0x77FE);
EndPoint tempRemoteEP = (EndPoint)senderEP;
				
s.ReceiveFrom(buffer, 0, 1024, SocketFlags.None, ref tempRemoteEP);

I get a response from the device that indicates that the device's IP address is 192.168.50.50, which is correct, but if I broadcast to 192.168.255.255 instead of 192.168.50.255 I do not get a response.

If anyone can give me more information regarding this please let me know. Any article or book refences would be welcome as well.

Thanks,
Einar
